The distance type micro-wave oven
The utility model relates to a kind of micro-wave oven, particularly a kind of distance type micro-wave oven.
Commercially available micro-wave oven generally all is directly to use manual operation at present, and the people directly contacts with micro-wave oven.Though microwave is very little to people's harm, but still there is the microwave radiation that may occur.Along with improving constantly of people's living standard, quality of life is also required more and more higher, press for the micro-wave oven of safety and reliability.
The purpose of this utility model aim to provide a kind of intellectuality, can remote operated distance type micro-wave oven, to overcome the deficiencies in the prior art part.
Distance type micro-wave oven by this purpose design comprises existing micro-wave oven and manual operation plate, and its architectural feature is that described micro-wave oven is provided with wireless remote control emission and receiving system.Described wireless remote controller can be infra-red remote control, radio wave remote control or ultra-sonic remote control.Described wireless remote control emitter is a remote control panel, and it finishes the setting of program with the auxiliary operation of human-computer dialogue display format, is stored, is encoded by single-chip microcomputer, and the working procedure coding that will have identifying information by the modulation wireless carrier is launched.Described wireless remote control receiving device is a master control borad, it is provided with wireless receiving circuit and control executive circuit, after it receives the wireless signal demodulation, by the single-chip microcomputer on the master control borad code signal identification, the errorless back reduction of affirmation code are also stored, single-chip microcomputer will carry out information processing according to current micro-wave oven state, output control signals to drive circuit, carry out micro-wave oven control.
The utility model is applied to wireless remote control technology on the existing micro-wave oven, make micro-wave oven have human-computer dialogue operation, the demonstration of Chinesizing menu, manual and wireless remote control optional feature, make the people can the remote-controlled operation micro-wave oven, avoid the microwave radiation that may occur, make it safety and reliability.This control technology not only can remote control, and also with the processing of micro-wave oven operative intelligence, as long as choose food variety and weight, micro-wave oven is regulated time and firepower automatically by micro computer, even also can cook out delicious food to the micro-wave oven operation is unskilled.
Accompanying drawing is the utility model one example structure schematic diagram.
Fig. 1 is the circuit working schematic diagram.
Fig. 2--Fig. 4 is respectively master, a left side, the vertical view of micro-wave oven.
Fig. 5--Fig. 7 is respectively master, a left side, the vertical view of remote control panel.
Fig. 8 is the operation principle block diagram.
Referring to Fig. 1, the circuit working principle is as follows:
Circuit comprises key input, liquid crystal display, single-chip microcomputer and four parts of infrared ray emission, is core with the single-chip microcomputer,, all the other each several parts of centralized Control.Capacitor C 1, resistance R 4 are formed automatic reset circuit, with the initialization of electric capacity charging realization system.Capacitor C 2, C3, quartz crystal OSC1 and C4, C5, OSC2 form single-chip microcomputer doubleclocking circuit, for the work of single-chip microcomputer provides clock signal.Single-chip microcomputer output/input port provides key-press matrix, as the operation input.The single-chip microcomputer delivery outlet provides liquid crystal display to drive.Resistance R 2, R3, triode N1, transmitting tube L1 constitute infrared transmitter, provide modulation signal by the single-chip microcomputer delivery outlet, are amplified by the N1 in the radiating circuit, and control infrared emission tube L1 carries out the signal emission.
Described remote control panel is provided with LCDs LCD and food variety, weight, selection of time operated key.Described single-chip microcomputer can be selected magnificent W741 of nation or the TLCS-47 of Toshiba series for use.Present embodiment is selected the W741E260 type for use.
Described remote control also can directly be operated on remote control panel, it is that instant coding of each operation and modulation wireless carrier are launched operation information that operation information externally carries out wireless output, master control borad is decoded after receiving the wireless signal demodulation, output control signals to drive circuit, carry out micro-wave oven control.
